An extension of the successful series of Librarian telepics, the series bowed Sunday night with an average 5.4 million viewers tuning in to the two-hour broadcast. That's just a hair above The Last Ship's live-plus-same-day premiere haul of 5.3 million viewers, meaning The Librarians now ranks as the most watched cable debut of 2014.

With an encore, the series totaled 7.3 million viewers — and pulled 2.9 million adults 25-54 and 2.3 million adults 18-49.

The Librarians was ordered to series in April, part of an increasing reliance on genre projects that looks to be further solidified by the recent appointment of Kevin Reilly as TNT and TBS' entertainment chief. Last Ship, Murder in the First and Legends are other TNT 2014 additions to get the green light for sophomore seasons.
